My sister always asks me what I’ve been up to. I say, “Nothing, just working.” Then five minutes later, I’ll remember my crazy life and I’ll tell her, “Oh, I interviewed Kim Kardashian and partied with Mark McGrath.”

My sister can’t understand how I could forget these things even temporarily.

But Wayne Brady does.

Brady — who will perform interactive improvisation Saturday at The Mirage — is so busy, he can’t remember chunks of his life. How busy? He hosts “Let’s Make A Deal,” stars on “Whose Line Is It Anyway,” has a recurring role on “How I Met Your Mother,” tours the world and appears on “Real Husbands of Hollywood.”

I asked him to name his highlight of 2013, and he said, “um,” and couldn’t recall 2013 very well.

“The entire year went by so damn fast, I don’t even remember portions of it,” he said. “It’s like it went right from New Year’s to being New Year’s again. Is that a byproduct of getting older? Because that’s weird.”

I told him, “You need to have someone follow you around with a camera, like in ‘The Truman Show.’ ”

“That would be great,” he said, “just so you can know what happened three weeks ago. ‘Oh, that was me naked dancing on top of the car at 3 a.m.?’ ”

Anyway, I informed Wayne Brady what Wayne Brady’s highlight was. It was when he was on the improvisation show “Whose Line Is It Anyway,” and he did an authentic job of pretending to be in “Grand Theft Auto.”

“That was real,” Brady said. “I’m a big gamer.”

In fact, he wanted to go crazy on the set of “Whose Line” by mimicking more “GTA” criminal stuff, but Brady couldn’t go that far on broadcast TV.

Brady said he has done some voice acting in video games. Which ones?

“I did some voice acting for the ‘Spyro’ series, and,” he said and thought hard, “something else I don’t remember. Crap!”
